Introduction to Density and Measurement Date performed: January 29 Introduction In this experiment the relationship between the mass of four different steel balls and its physical dimensions were investigated. Ball bearing were measured on an analytical balance with each having a different mass. In addition, the diameter of balls were measured using a Vernier. The results were compared to the actual volume of steel. Results/Observations Ball bearing # 1 (smallest) 2 3 4 (largest) Weight 8.3504 16.2959 28.1425 66.7313 Diameter 1.34 1.62 1.92 2.63 Calculations Ball #1 Density= mass/ volume 6.62818= 8.3504 /1.259833108 Surface area = 4*3.14*(diameter/2)^2 4*3.14*(1.34/2)^2= 5.641043769 Volume = 4/3*3.14*(diameter/2)^3

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
